It is a semi-deciduous plant that has beautiful white flowers that bloom in the winter, making it an excellent plant for a winter garden. The plant can be propagated by seed, cuttings, or division.
Propagation by Seed
To propagate the Dicoma capensis Less. by seed, it is recommended to collect the seeds in the fall after the flowers have died. The seeds should then be sown in a well-drained soil mixture in a seed tray. The tray can be placed in a warm, well-lit area and should be kept moist.
